**What is Lithium Iron Phosphate?**
Lithium iron phosphate (LiFePO₄) is a type of cathode material used in lithium-ion batteries. It stands out for its high discharge capacity, low cost, non-toxic nature, and environmental friendliness. Countries around the world are striving to achieve large-scale industrial production of this material. However, one of its limitations is its low tap density, which can affect the battery’s overall energy capacity. The most common production method today is high-temperature solid-state synthesis, resulting in stable product performance.
The performance of lithium-ion batteries largely depends on the quality of their positive and negative electrode materials. Lithium iron phosphate as a positive electrode material has only gained attention in recent years. In July 2005, China developed large-capacity lithium iron phosphate batteries, which quickly became popular due to their excellent safety and long cycle life—key factors for power batteries. These batteries can withstand 2,000 cycles at 1C charge and discharge. They are also highly safe: even when overcharged up to 30V or punctured, they do not catch fire or explode. This makes them ideal for use in electric vehicles, where frequent charging and discharging are required. With advantages such as non-toxicity, low cost, and long service life, lithium iron phosphate is considered an ideal cathode material for next-generation lithium-ion batteries.
**Lithium Iron Phosphate Production Ranking**
In 2017, 21 domestic companies produced a total of 74,400 tons of lithium iron phosphate, maintaining a level similar to the previous year. Among the major manufacturers, Betray, Sublimation Technology, and BYD were the top three, with significant changes in rankings compared to 2016.
The market environment for lithium iron phosphate was vastly different in 2016 and 2017. In 2016, due to restrictions on ternary material-based commercial vehicles, lithium iron phosphate experienced explosive growth, with output reaching 73,900 tons—an impressive increase of 130% from the previous year.
However, starting in 2017, government subsidies for new energy vehicles began to prioritize higher energy density batteries. As a result, ternary materials gained more favor in commercial vehicles, leading many manufacturers to shift toward using those instead. This posed a challenge for lithium iron phosphate, which had previously dominated the new energy vehicle market. Companies like Jiangxi Jinli, Zhejiang Ruibang, and Henan Langtai saw significant declines in production that year. Many projects planned in 2017, such as those by Deyang Weixu, Jiangxi Tong Li, and Sanqiu New Energy, struggled to reach mass production due to the changing market conditions.
**Production Yield Overview**
In 2017, both Betray and Sublimation Technology saw substantial growth. Betray, known for its leadership in anode materials, leveraged its strong relationships with major battery manufacturers to quickly expand into the positive electrode material market. Sublimation Technology, on the other hand, benefited from stable supply chains and the expansion of its Yichun plant in Jiangxi, leading to increased overall production.
